You need resistors from the grids of the 12AU7s to ground - it looks like maybe they were there at one point and then accidently removed.
What is the input tube - I can't quite read the schematic. ECC???. FWIW, I much prefer octals over 9 pin tubes. I would replace the 12AU7 with a 6SN7. Kowever, as others have mentioned, it may not be needed at all.
